Title: Fertility and Development
1Fertility and Development
2Measures of Fertility (1)
- Birth rate (or crude birth rate) The number of
live births per 1,000 population in a given year.
- Growth rate The number of persons added to (or
subtracted from) a population in a year due to
natural increase and net migration
3Measures of Fertility (2)
- General Fertility Rate
- GFR (B / FP15-44) 1,000
- FP15-44 female population aged 15-44
- Age specific fertility rates
- Total Fertility Rate (TFR)
- Child-Woman Ratio (CWR)
- CWR0-4 (P0-4 / FP15-44)
- CWR5-9 (P5-9 / FP20-49)

5TFR and replacement fertility
- TFR explores replacement fertility levels
- A population with replacement fertility will stop
growing - In country like US with low mortality rate 2.1
TFR is produces replacement level fertility where
as for Sierra Leone TFR should be greater than 3
6TFR in Europe and the USA
7Fertility rates in Asia
8TFR decline in some European countries
9Evolution of fertility rates
10European Fertility Rates - 2001

11Fertility decline by age groups
12ICPD conference
- Cairo 1994
- Many governments pursued demographic policies
that time to decrease their population - The number of developing countries that view
their population growth as too high or too low
has declined - Developed countries are worried about declining
fertility and population aging

14Situation of growth in developed countries
- Fall in death rates was relatively gradual due to
trail and error of innovation - Technology for improving production, sanitary
methods and medical advances has to be discovered
or invented - Due to norms of late marriage birth rates never
increased dramatically - Population growth was not a violent explosion
15The decline in fertility rates in the EU
- Women (and families) are deciding to have less
children than ever before - Total fertility rates in the EU are the lowest in
the world, bar some countries in Eastern Europe
and Japan - Fertility decline started in the mid 1960s
- Early declines in the North (Denmark, Finland,
Germany, Luxembourg and Sweden) Demographic
core/periphery divide - Subsequent and more dramatic decline in the
Mediterranean countries (Italy and Spain now with
some of the lowest TFR in the world) - Short-lived rebound of fertility rates in Sweden
and other Scandinavian countries in the early
1990s
16The decline in birth rates in Europe
- Lower number of marriages and marriages later in
life - Unstable marriages and growing divorce rates
- Increase in cohabitation
- Increasing age at marriage
- Participation of women in the labour market
17Situation of birth and death rates in the
developing countries
- The decline in mortality was widespread and
sudden - Medical technology was already available
- Insecticides such as DDT provided cheap way for
bringing down malaria - Infant mortality rates also declined considerably
- decline in death rates and increase in birth
rates were faster
18Fertility and missing markets
- Children are substitutes for various missing
markets especially social security in the old age - Developed countries Social security fund or
employer subsidized retirement plan along with
medical insurance - In developing countries, many of these
institutions are totally missing and the
available institutions are only for formally
employed (not for agricultural and urban informal
sectors)
19Mortality and fertility
- Infant mortality is 150-200 per 1000 births in
some developing countries - Added to this after this barrier childhood
diseases are preponderant - Also there is a possibility that a child might
not be an adequate income earner - Lastly a child might not look after the parents
in their old age - All these situations compel parents for more
children to overcome all these barriers
20Gender bias and fertility
- Son preference forces couples to have more
children for the need for more sons - Culturally and economically sons are beneficial
for parents in many Asian countries which compels
them to increase their number of children till
they achieve the desired number of sons - Study in Bangladesh shows that widows can hold in
to land if they have able-bodied sons ( Cain) - Also for agricultural families more sons means
more labor (North and South India Tim Dyson)
21Costs of Children in the poor countries
- Because children are an investment rather than
a consumption good the expected return of the
investment is given by child labor and financial
support for parents in old age - Parents have children up to the point at which
their marginal economic benefit is equal to
marginal cost
22Why Children are beneficial in Developing
Countries ?
- In sum
- Infant/child mortality remains high
- Sources of child labor remittance income later
on - Social security/safety net for elderly poor
- Low child-rearing cost, esp. low opportunity cost
of womens time
23Impact of high fertility in developing countries
????
- Mutual causation means that rapid population
growth with its usual accompaniments of early
first births, large families, high child-adult
ratios and near spacing of siblings may be not
only a cause of poverty through the above
mechanisms, but also a consequence of poverty
probably due largely to constraints on, and
rational behavior by, the poor. - Eastwood and
Lipton

25Household theory of fertility
- Family size is a decision taken at the
microeconomic level by households based on a
rational economic decision on demand for
children - Income effect Higher income allows for larger
family size - Substitution effect Higher cost of children
implies smaller family size - Other theories
26Stage of Demographic Transition and population
requirement
- Population growth may be good in the beginning
- Besides population growth factors like political
stability, cultural resources, and economic
efficiency may be much more important ???
27Response of different countries
- Africa Namibia, Tanzania and the Sudan
officially inaugurated policies to reduce
population growth - Most of the Asian governments are satisfied about
their growth rates (especially China and Korea) - Europe Portugal, Romania, and Italy are
concerned about low population growth and Croatia
inaugurated policy to increase fertility - In Latin America many countries consider their
population growth rates to be satisfactory.
(exceptions densely populated areas of the
Caribbean and Central America - North America US and Canada, Australia and New
Zealand are satisfied with their population
growth rates
28Did family policies work?
- Some claim that the impact has been weak
(Gauthier Hoem) - Others suggest that family policies have had an
impact - The actual evidence is inconclusive
- Lack of adequate family policies may have
contributed to the decline in fertility in
southern Europe - Some countries with more generous family policies
(Sweden, Finland, Denmark, France, the UK) tend
to have slightly higher fertility rates - But countries with similar family policy regimes
differ in their fertility rates
